SAS Hv-BALANCE.

SPECIFICATION forming' part of Letters Patent No. 478,352, dated July 5, 1892.

Application filed March 31, 1892. Serial No. 427,232. (No model.) Patented in Canada April 26. 17892, No. 38,706.

T0 all whom t may concern:

Be it known that I, JAMES JOSEPH OCoN- NOR, of the town of Oakville, in the county ot' Halton, in the Province of Ontario, Canada, have invented a certain new and Improved Sash Balance, (for which I have obtained Letters Patent ot` the Dominion of Canada, dated the 26th day of April, 1892, and numbered 38,70G,) of which the followingisaspeeication.

The object of the invention is to provide a simple device by which a WindoW-sashor vertically-sliding door shall remain balancedor supported at any desired altitude without either balance. weight, or spring; and it consists, essentially, of a exible band wound around or partially around a stub'txed-to the sash or sliding door, the ends of the ilexible band being fixed to the frame in which the sash or door slides, substantially as hereinafter more particularly explained.

Figure l is a View of a window-frame having its sashes supported by myimproved halance, a portion of the Wood-work being broken away to expose the location of the device. Fig. 2 is an enlarged perspective detail of the flexible band Wound around the stub.

By the adoption of my invention a device is secured by Which the heaviest kind of sash or vertical-sliding door may be supported so' as to be adjusted vertically with the slightest possible exertion, and the said effect desired is secured Without the balance-Weight so commonly used or any form of spring, which is so liable to get out of order.

A represents a flexible band, made of light ribbon-steel or Aany other flexible material found suitable for the purpose.

B is acasting having formed thereon a fixed cylindrical portion or stub B, preferably cast thereon and sunk into a recess made in the sash C or in the frame D, as shown. When the casting B is sunlcin the sash C, the ends of the band A, which is Wrapped spirally around the stub`B, are connected, respectively, to the top and bottom of the frame D, and when `the casting B is in the frame D the ends of the band A, which is Wrapped around the said stub, al'e connected to the top and bottom of the sash C, as shown. In

this Way the band A'supports the sash,which l sash, however, may be moved freely up and down, the friction ofthe band upon the fixed stub B being suicient to support the sash. As already indicated, it makes no dierence whether the casting with its stub is fixed to the sash or to the frame.

Vhat I claim as my invention is- The. combination of a sash and its frame with a casting B, attached to `said sash and having a fixed stub B, and the 'lat band A, wound spirally around said stub and having its opposite ends attached to the frame, substantially as described.
